This device is developed for use at test benches to collect all aerosols produced when testing fuel injection valves on shore and onboard vessels. It replaces the connection to the ships existing ventilation system. The device functions as a closed unit, and uses re-circulation of the air. Oil aerosols are effectively sucked out in the transparent acrylic container by using a vacuum. The aerosols are saturated and collected for draining and recycling in the filter.
